Grease gun.

Hi, I have been given a laser grease gun(bulk loading gun). But when I pull the piston back it doesn't stay at the back of the gun it springs forward. So I can't get the grease in before it springs forward. Am I doing something wrong?
 
If it's like mine there is a handle attached to a chain that pulls the piston back, the chain link locks into a slot where it pulls through the hole. Load it by putting the end of the tube in a tub of grease and pull back on the piston, like a syringe, and lock the chain in the slot. Screw the tube back into the gun then release the chain from the slot to put the grease under pressure - there should be a bleed nipple somewhere to expel the air otherwise the gun wont pump grease.

Will the piston lock if you twist the handle?

No, that's the problem. It should have a little piece of metal on the piston that locks when you pull the piston back and twist but there's nothing there. No worries I will keep a look out for a new one. I'm gutted because I wanted to do some greasing tomorrow, on well penny more to be getting on with. I have finished my roof, the new material I put in has worked really well.
 
Can you wedge a piece of wood or something in between the handle and the top of the piston tube to hold it in place.

OK, my last idea is to split a piece of tube (copper would be good) enough to fit over the piston shaft.

Hi panky I took my grease gun to my local motor factors and they swapped if for me.fair play as I didn't get it from there. I just need a 0891 nylon flexi hose for my laser 0240 gun.
 
Yeah they said they would, I know the guy really well. I think it was because it's the same one that they stock.
 
Hi one of my friends has asked me if a pressol pistol action grease gun is any good. He's been offered it for £10.

If I see one more grease nipple........
